Subject: API Key Validation Issue (pushnotifications.io) – Cloudflare 403 Error

Dear Support Team,

I am contacting you because I’m experiencing an issue with the API key validation for the pushnotifications.io service in your Super Progressive Web Apps plugin.

When I try to validate my key, the operation consistently fails. By enabling WordPress debugging, I was able to get precise information about the cause of the problem.

Technical Analysis of the Issue:

Your plugin sends a POST request to the URL https://pushnotifications.io/api/validate/user to verify the key. However, this request is being blocked and receives a 403 Forbidden error in return.

Analyzing the server response headers clearly shows that Cloudflare’s bot protection (used by pushnotifications.io) is intercepting and blocking my server’s request. The cf-mitigated: challenge header and the "Enable JavaScript and cookies to continue" response body confirm this diagnosis.

In short, your push notification partner’s firewall is mistaking my server for a bot and preventing it from validating the key.

Actions Already Taken:

For your information, I have already performed the following checks without success:

• Checked for conflicts with other plugins or my theme.
• Confirmed that my site is on HTTPS.
• Verified the integrity of the API key.

Therefore, it seems the issue is not with my WordPress configuration but is due to an external block.

My Question:

Are you aware of this compatibility issue with Cloudflare’s protection on pushnotifications.io? Is there a workaround or a specific configuration to apply so that the validation can be completed successfully?

Thank you in advance for your time and assistance.

Best regards,
